As we have reported, silver nanoparticles were mostly taken up by hMSC through clathrin-dependent endocytosis and macropinocytosis but not through caveolin-dependent endocytosis, as shown by flow cytometry (scattergram analysis) [77].

Furthermore, confocal laser scanning microscopy (CLSM) and flow cytometry were used to monitor the nanoparticle load of individual cells. As a probe we chose tailor-made PLLA

Flow cytometry provides sound statistics due to the large number of cells evaluated in a short time. Nevertheless, it does not deliver spatial information about the position of nanoparticles interacting
